Programmable DC Electronic Load 63600 Series Operation & Programming Manual
Dynamic Load Mode
There are two Operation Modes for dynamic load: Dynamic load mode and Dynamic load
frequency sweep mode. Press
sweep mode.
Dynamic load operation offers the user to program 2 load levels (Load1 and Load2), load
durations (T1 and T2), slew rates (Rise and Fall), and Repeat times (RT). During operation,
the loading value is switched between those two load levels according to your specific setting
parameters. The Dynamic Load is commonly used for testing the UUT's performance under
high speed, transient loading condition.

The STATic/DYNAmic functions can also be selected through
module.
Slew Rate (Rise, Fall A/
Slew rate determines the rate at which the current input of a module change to a newly
programmed value. There are two slew rate values, which are rise rate and fall rate.
Voltage Ranges (Low, Middle, High)
There are three voltage ranges for voltage measurement and Von voltage setting. The low
range provides better resolution at low voltage measurements. If the value is over the
maximum of low range, you must select the middle range. When the value is over the
maximum of middle range, you must select the high range. The CC mode voltage range
selection is in configuration setting.
Repeat times (times)
The Load provides a unique simulation capability, which allows users to set the number of
the period times. When the times is set a limited period times, the load is automatically off till
the period time is over. If you want to continue the load with unlimited times, just to set the
value to be zero.
